用美国杰斐逊实验室的CLAS-12谱仪测量了从非极化质子靶上独家电产生K^+\Lambda$和K^+\Sigma^0 $末态的束流反冲转移极化。在能量为6.535~GeV和7.546~GeV的束流上进行的测量跨越了四动量转移Q^2 $从0.3 ~ 4.5~ GeV^2 $和不变能量W$从1.6 ~ 2.4~GeV的范围，同时覆盖了K^+$的整个质心角范围。这些新的数据扩展了CLAS现有的超子极化数据，在类似的运动学范围内，但从一个显着更大的数据集。它们是对世界数据的重要补充，可以更好地探索奇异产生过程中的反应机制，进一步了解激发核子态的光谱和结构，并更好地了解非微扰动力学制度中的强相互作用。
Beam-recoil transferred polarizations for the exclusive electroproduction of $K^+\Lambda$ and $K^+\Sigma^0$ final states from an unpolarized proton target have been measured using the CLAS12 spectrometer at Jefferson Laboratory. The measurements at beam energies of 6.535~GeV and 7.546~GeV span the range of four-momentum transfer $Q^2$ from 0.3 to 4.5~GeV$^2$ and invariant energy $W$ from 1.6 to 2.4~GeV, while covering the full center-of-mass angular range of the $K^+$. These new data extend the existing hyperon polarization data from CLAS in a similar kinematic range but from a significantly larger dataset. They represent an important addition to the world data, allowing for better exploration of the reaction mechanism in strangeness production processes, for further understanding of the spectrum and structure of excited nucleon states, and for improved insight into the strong interaction in the regime of non-perturbative dynamics.
